Timed-dose control panels from Clarus Environmental provide residential and commercial customers with a reliable means of controlling single-phase pumps in onsite installations. A programmable timer activates a magnetic motor contactor to turn the dose pumps on and off. A high- or low-water condition will override the timer to turn the pump on or keep the pump from running dry. An alarm float activates the audio/visual alarm system, indicating a high liquid level.  Simplex or duplex models are available. Panels include a Test/Normal/Silence switch, which allows the horn and light to be tested or silenced in an alarm condition. 800/928-7867; www.clarusenvironmental.com.
